INSTALLATION

WARNINGExplosion or Fire Hazard.Can cause severe personal injury, death or property damage.Observe all safety requirements each time a control is installed on a burner.

When Installing this Product...1. Read these instructions carefully. Failure to follow

them can damage the product or cause a hazardous condition.

2. Check the ratings given in the instructions and on the product to make sure that the product is suitable for your application.

3. Installer must be a trained, experienced service technician.

4. After installation is completed, check out product operation as provided in these instructions.

WARNINGElectrical Shock Hazard.Can cause serious personal injury or death.Disconnect power supply before beginning installation. More than one disconnection can be involved.

Mounting

NOTE: On flange models, remove the label holding theO-ring in place and make sure O-ring seal is in place before mounting the pressure switch on the valve.

The C6097 models allow NPT or flange (directly to valve) mounting. The NPT models have a hexagonal fitting with a 1/4 in. NPT tapping, which is the high pressure connection, in differential applications. The Atmospheric Pressure Reference Port is 1/8 in. NPT tapped. In differential pressure control applications using air only, connect the lower pressure to this Atmospheric Pressure Reference Port. See Fig. 1.

Both the flange mount and NPT mount models are supplied with an Integral Vent Limiter. External vent line is not required. If necessary, this 1/8-in. atmospheric vent fitting can be used for the vent line connection.

C6097 models with flange mount can be fitted directly to Honeywell Integrated Valve Train (model specific). See Fig. 2 and Table 1. The flange mount models vent internally, with no external tap.

Mount the C6097A,B in any position.

Leak CheckAfter installation, perform a leak check on the pressure switch:

1. Turn on main gas. Make sure gas has reached the pressure switch (e.g., high gas pressure switch)

2. Check installation for gas leaks using a gas leak detector or a soap solution.

Installation

WARNINGExplosion or Fire Hazard.Can cause severe personal injury, death or property damage.Observe all safety requirements each time a control is installed on a burner.


Installing the Position Indication Lamp Kit (See Fig. 4)

1. Remove the cover from the C6097 by removing the screws in the upper left and lower right quadrants of the cover.

2. Place the lamp in the slot to the right of the dial, in the upper right-hand corner of the C6097, with the base down. Run the two lamp wires through the slit in the upper left corner of the lamp slot.

3. Place the nut in the hexagonal depression in the lower left-hand corner of the C6097.

4. Place the terminal plate over the nut and fasten the terminal plate to the C6097 with the screw through the bottom hole in the terminal plate.

5. Place the captive screw through the terminal lug on the shorter wire and fasten the wire to the terminal plate with the captive screw secured by the nut under the terminal plate.

6. Using Fig. 5 or 6 for reference, fasten the terminal lug on the longer lamp wire to either the normally open (NO) or normally closed (NC) terminal of the C6097. Fig. 4. Installing the Position Indicator Lamp Kit.

Position Indicator Lamp OperationThe Position Indicator Lamp will light when the C6097 Pressure Switch opens and provides power to the lamp (see Fig. 5or 6). An option alarm circuit can also be connected as shown in the same figures.

WIRING


Make sure that all wiring agrees with all applicable local codes, ordinances and regulations. An opening is provided to accommodate rigid conduit or armored cable for line voltage operation (see Fig. 3 and 4). Do not overload the switch contacts (see Switch Ratings in the Specifications section). The switching schematic is shown in Fig. 5.

SETTINGS AND ADJUSTMENTS

Pressure Setpoint AdjustmentTo adjust the pressure setting, turn the setpoint adjustment dial (Fig. 3, 4 and 5) clockwise to increase the pressure setting and counterclockwise to decrease the pressure setting.

OPERATION AND CHECKOUT

OperationThe manual reset C6097A diaphragm actuates the snap-acting switch to break a control circuit and lock out when pressure falls to the scale setting. The recycle C6097A models recycle automatically when the control circuit returns to scale setting plus differential.

The manual reset C6097B diaphragm actuates the snap-acting switch that breaks a control circuit and locks out when the pressure rises to the scale setting. The recycle C6097B models recycle automatically when the control pressure falls to the scale setting minus differential.

Manual ResettingThe C6097A manual reset models lock out when pressure falls to the scale setting and require manual resetting after the pressure rises to scale setting plus differential to resume normal operation.

The C6097B manual reset models lock out when pressure rises to the scale setting and require manual resetting after the pressure falls to scale setting minus the differential to resume normal operation.

To reset, once normal operating pressure is restored, push the reset button in as far as it goes, then release.

IMPORTANTLockout models cannot be made to recycle automatically by permanently holding in the reset lever.

Checkout

C6097 Gas Fuel Application1. Set cutoff pressure.2. Open main supply line. Depress reset lever on lockout

models until switch makes control circuit.3. Set controller and limit switch to call for heat.4. For C6097A: Close the manual gas shutoff valve. C6097

should open control circuit when pressure reaches cutoff point.For C6097B: Open the manual gas shutoff valve, wait a few minutes for the pressure to rise; then lower the scale setting until the switch breaks control circuit and locks out.

5. For C6097A: Open the shutoff valve, return the pressure switch to its original setting and press the reset button (if necessary).For C6097B: raise setting to normal and press reset button (if necessary).

6. Allow system to operate through at least one complete cycle to make sure all components are functioning properly.

C6097A Air Application1. Set cutoff pressure.2. Turn on fan.3. Block fan inlet or filter area. Switch should break control

circuit when pressure drops to cutoff point. Manual reset models lock out.

4. Remove obstruction. Press reset lever (manual reset models) and allow system to operate through at least one complete cycle to be sure all components are functioning properly.
